I have, for many years, fished a caddis pupa soft hackle pattern which has worked wonderfully for me and others. If I can locate a picture, I will post it as well.

Cannot speak to effectiveness, as have not had a chance to fish it, but look forward to doing so.
Here is Hans Weilenmann's photo of the soft hackle version I alluded to:
